How many phosphate groups are present in a single strand of DNA?

Question

Quizplus · Accepted Answer

Each nucleotide in DNA contains one phosphate group, so the number of phosphate groups in a single strand of DNA is equal to the total number of nucleotides, which is equivalent to the sum of the number of adenine, thymine, guanine, and cytosine bases. Therefore, option D is correct. Option A and B are incorrect because the number of adenine bases does not determine the number of phosphate groups, while option C is incorrect because it only considers two of the four possible bases in DNA.
